Homework:

-Describe and explain that the complex set of systems found in multicellular organisms are made up of different kinds of tissues and organs which are, in turn, composed of differentiated cells -Select several body systems and explain the role of cells, tissues, and organs in the systems selected that effectively carry out a vital function for the organism, such as:Obtaining food and providing energy, Defense, Reproduction, Waste Removal, Breathing VSC Content Standard: Recognize and explain that human beings, like other organisms have complex body systems of cells,tissues, and organs that interact to support an organisms growth and survival.

What’s in the Blood? Plasma Red Blood Cells White Blood Cells Platelets

Components of the Blood **All of this stuff floats around in the Plasma!!!!!

Red Blood Cells

White Blood Cells & Platelets

Plasma- Carries materials, molecules that come from the breakdown of digested food. Plasma- Carries materials, molecules that come from the breakdown of digested food. Proteins make it yellowish in color Proteins make it yellowish in color Carries vitamins and minerals Carries vitamins and minerals Carries chemical messages Carries chemical messages About 55% of blood is made up of plasma About 55% of blood is made up of plasma Plasma

Red Blood Cells Red Blood Cells- Take up the oxygen from your lungs and deliver it to the rest of your body Red Blood Cells- Take up the oxygen from your lungs and deliver it to the rest of your body Are produced in the bone marrow Are produced in the bone marrow Mostly made of hemoglobin Mostly made of hemoglobin Hemoglobin binds with oxygen in the lungs and releases it as it travels through the body. Hemoglobin binds with oxygen in the lungs and releases it as it travels through the body. Picks up some carbon dioxide, but most is carried by the plasma Picks up some carbon dioxide, but most is carried by the plasma

White Blood Cells White Blood Cells- These are the body’s disease-fighters White Blood Cells- These are the body’s disease-fighters Recognize invaders and alert the rest of the body Recognize invaders and alert the rest of the body Produce chemicals to fight Produce chemicals to fight Only one white blood cell for every 500/1000 red blood cells Only one white blood cell for every 500/1000 red blood cells Bigger than RBC’s Bigger than RBC’s

Platelets Platelets- These are cell fragments that an important part in forming clots. Platelets- These are cell fragments that an important part in forming clots. Produce a chemical called Fibrin Produce a chemical called Fibrin Fibrin weaves a net of tiny fibers across the cut in the blood vessel. Fibrin weaves a net of tiny fibers across the cut in the blood vessel. The “net” traps the blood cells The “net” traps the blood cells Clot Forms, bleeding stops Clot Forms, bleeding stops
